CONCLUSIONS: <br /> Soil impacts extend vertically from the base of the dispenser area overexcavation to <br /> approximately 70 feet bgs, petroleum hydrocarbon concentrations attenuate at 80 feet bgs <br /> Groundwater impacts at the water table are limited to MTBE at concentrations of 11 and 18 ppb <br /> in MW-3 and MW-4, respectively, and TPHG in MW-3 at 67 ppb <br /> Deep groundwater {80 feet bgs} is impacted by TPHG, BTEX, and MTBE Concentrations in <br /> MW-6 are 2,300 ppb, 22 ppb, and 2 2 ppb, respectively, for TPHG, BTEX and MTBE MW-7 <br /> contained MTBE at 16 ppb This is the first sampling of the deep wells The extent of the deep <br /> impacts is not defined The source of the deep groundwater impacts appears to be the soil <br /> impacts extending to approximately 70 feet bgs <br /> The owner of adjoining property to the east and north of the subsea site is exploring a purchase <br /> of the subject site with probable use as parking <br /> 822121/igsrol 3 03/13/01 <br />
